Hi! Sorry for late response, was doing school stuff and had problems trying
to get nvidia drivers on 4.19-rc3 to work.
setting options snd-hda-intel model=alc668-headset
in /etc/modprobe.d/alsa.conf
on the 4.18.7-gentoo kernel it changed nothing (exept for the layout in
alsamixer - that is better).
I checked the source code in sound/pci/hda/patch_realtek.c and there seems
to be no difference between the code in 4.18.7 and 4.19-rc3
There is a difference, and this option didn't take effect on 4.18.
You need 4.19-rc for allowing that option.

I could try testing more, but I am not good with sound tests without gui.

Also,
hda-verb /dev/snd/hwC0D0 0x20 0x500 0xc3 and
hda-verb /dev/snd/hwC0D0 0x20 0x400 0x00
Makes the issue appear again!
So it seems like 0xc3 toggles it.
Good to hear that you nailed it.
So this looks like that the alc668 headset mode would work.
What happens if you pass model=alc668-headset option with 4.19-rc
kernel?  Does it make things working?

Can confirm that running:
hda-verb /dev/snd/hwC0D0 0x20 0x500 0xc3 and
hda-verb /dev/snd/hwC0D0 0x20 0x440 0x00
Fixes the issue completely.
Thanks to everyone who helped!

I might not get around to writing the fix myself, but, here's the
COEF's from within Windows. I've marked the ones missing inside the
main init function. So, if anyone else wants to add these in, feel
free.

That was without running the program (sorry)
This is output when running program:
Before there was no "Current verb...."
They came when I opened up windows microphone settings. (something I
